Effect of TeO2 addition on the gamma radiation shielding competence and mechanical properties of boro-tellurite glass: an experimental approach

Journal of Materials Research and Technology, 2022
We experimentally investigated the effect of TeO2 on the radiation-shielding competence of a BaO–MoO3–B2O3 glass system. Two gamma-ray sources (137Cs and 166Ho) and a scintillator detector (sodium iodide (NaI(Tl)) were utilized to measure the attenuation

Influence of WO3 content on gamma rays attenuation characteristics of phosphate glasses at low energy range

Open Chemistry, 2023
The radiation attenuation characteristics of WO3-Li2O-ZnO-P2O5 glasses have been examined using Phy-X software. The linear attenuation coefficient is correspondingly increased with the inclusion of WO3, which indicates the existence of a reducing ...

Hazardous radiation protective glasses for medical and research laboratories

Heliyon, 2023
In the current study, the bismuth oxide (Bi2O3) content was inter-substituted with gadolinium oxide (Gd2O3) in sodium borate glass. Glass sample density and molar volume values show a reverse trend. The optical transparent radiation shielding glasses are
